The talent show phenomenon that is The Voice is now in its third season in South Africa and is proving as popular as ever. It has just entered the live show' phase, broadcast from Mosaiek Teatro in Fairland, Johannesburg and aired on M-Net, DStv 101. This year, this exciting section of the TV show is bringing a brand-new audio experience to its studio audience, courtesy of L-ISA Hyperreal Sound technology by L-Acoustics and DiGiCo mixing consoles, provided by the show's full technical supplier, Mutli-Media.
Multi-Media has worked with The Voice since the popular competition hit African soil four years ago. During this time, the company has grown and become more involved in live events. At the beginning of this year, it decided the time was right to invest in a top-end audio system, initially purchasing 30 L-Acoustics Kara, 12 SB18, four KS28 and seven LA12X amplified controllers, adding a further 18 Kara, four SB18 and five LA12X for the Mosaiek Teatro L-ISA configuration.
Early in his career, Multi-Media audio engineer Adriaan van der Walt recognised the limitations of stereo systems when trying to create a natural sounding mix. He became interested in how technology would develop to achieve a closer representation of how sounds are perceived by the human ear.
I always jumped at the opportunity to work on quadrophonic and surround shows, he says. These were few and far between and some had greater levels of success than others. There was generally very little correlation between the setup in a studio and a large format PA system - it was really hit and miss! Then L-ISA caught my attention and I knew it would be a game-changer. L-Acoustics is a brand I trust and is always leading edge, setting trends and standards for the rest of the industry to follow. For me, moving to L-ISA was a no-brainer. I knew it would have huge benefits for a strong production like The Voice. When I presented the idea to the production team, they were convinced, too.
Van der Walt and DWR's Chris Pugh travelled to the manufacturer's head office near Paris for an extensive four-day L-ISA training session. It was very informative with a great deal of information to absorb, but the friendly and welcoming spirit that is present at L-Acoustics made it a special experience for me, says Pugh. I had dreamed of visiting L-Acoustics for 15 years and Adriaan and I loved every moment. We couldn't wait to get back to South Africa to get started.
The Mosaiek Teatro configuration sees five arrays of nine Kara each, positioned across the width of the stage as a Scene system. The KS28 subs are flown centrally, providing seamless coverage across the venue. Six Kiva II per side act as the Extension system and provide a wider panorama to the audio experience. Front fills comprise two X12 and, due to the width of the venue, there are an additional two ARCS WiFo flown per side to cover the outer sides of the venue. For stage monitoring, Multi-Media's Simon Panos has used two X12 flown in the lighting grid and two X12 on the side of the stage.
Control is via a DiGiCo SD10 running the latest firmware. It has a couple of new features that tie L-ISA and DiGiCo together, says van der Walt. The configurability of the SD Range is incredible. I set it up so that, in no more than three button pushes, I can be anywhere I need to be and do anything I need to do. Of course, it takes a bit of time to lay it all out and programme it but, once you are in that operation mode, it really is a breeze to work on it.

The DiGiCo system integrates Waves Multi-Rack, L-ISA Controller, Multitrack Recording and a busy Optocore backbone. There was a lot of routing and insert patching that had to happen in the background, he said. We almost managed to max out the first Optocore loop - there are only 40 audio paths left out of 500.
For van der Walt, the SD10 is an extension of himself with the console's layout going hand-in-hand with his thought process: That's the beauty of it; once you've laid it out, it becomes an extension of your thoughts because you don't have to tap around to get where you need to be. You think something, you tap once or twice, and you are there.
The Voice is a complex and busy show, sometimes with only 15 seconds between performances and van der Walt is able to jump from one to the next with great ease: The way the SD10 recalls fader banks over the entire console with just a Snapshot is truly amazing. We have rehearsed the show so much that it's really just about recalling Snapshots and adding fine adjustments during the live broadcast.

While there are familiarities in how the audio system is set up, the approach to mixing is, says van der Walt, a departure from what he is used to: The experience means applying yourself in a new way. Your creative input becomes more valuable with L-ISA. It gives you the opportunity to interpret the music and place things where you think they should sit spatially. It's incredible how this, in turn, affects the mix; the possibilities are endless.
In the weeks leading up to the first sound check van de Walt spent many a night awake, imagining what they were going to do with, amongst other things, spatial place
